mich,
why dun u consider leaving K whole day in CC? u may think after lunch is sleeping and nothing much.. but even then, it's still being together with the other kids.
For EJ, cos he is full day, the school bathes him, so he get to see other kids go toilet etc.. so he kind of pick up toilet training.. then after nap, there is still an activity. Plus he also gets to play with older kids cos for afternoon, they will mix them (cos EJ's CC is small). So i feel that overall, being on full-day has it's advantages too. Can help to train the kids to be more independent and mix better with other kids. Just my thoughts la. something for you to think about.
